Burst Pressure Probability
Prior Post w/original data and images UPDATE: In the couple plots below, the minimum dimension has been changed to aspect ratio (minimum dimension/maximum dimension): For constant perimeter: alpha=1.1930, beta=.2005, gamma= -0.1380 And for constant area: alpha= -0.1624, beta= -0.0060, gamma=0.2922 In my last post I explained an experiment where multiple features were put on a single sample…
pnc-Si degrades into silicic acid
Over the past month, I’ve posted some results of a colorimetric assay for silicic acid. Previous posts are here and here. These results showed that the assay detected silicic acid after pnc-Si and PSi degraded. However, bare silicon wafers also yielded silicic acid, according to this assay. Since pnc-Si samples have the Si well-side surface,…
Pressurized rerun with w670
Previous Post The previous w670 pressurized flow gels showed one trial with a lower cutoff than w673 and one trial with nothing passing through. This experiment was run for 40 min and in each case I saw only 0-3 uL fluid passing. I used the last couple of samples from this wafer to attempt a…
w302 Permeability
Wafer 302 appears to have no pinholes and held up pretty well in the centrifuge, up to 5psi for many hours in a wet-wet format. Here are some quick numbers on flow rate over 2 hours, 3.3psi, including radial position:1x PBS (no protein)68 uL (r=4.1)91 uL (r=4.1)99 uL (r=4.5) Using Jim’s new equation. 99uL of…
Water Permeability – Looking at the data
So I talked a bit with Philippe today about the water permeability data, and he suggested that I try to see if there’s a correlation between what the histogram looks like and the experimental permeability’s relation to the theory. I pulled out all the histograms and here’s what I could find. Two of the membranes…
RTP Ramp Rate Effect on 6W Bias pnc-Si Stack Increases Pores Size Slightly
Purpose: We want to know the effects of the RTP process on pore size, pore density for the biased films coming out of the AJA. I believe that the RTP ramp rate is important for forming bigger pores. Some work (Joe Qi Thesis) has indicated that the pores come out more circular as the wafer is…
